Abstract

1. Continuous process for the preparation of propylene oxide, which comprises the preparation of an organic solution of percarboxylic acid by reacting hydrogen peroxide with a carboxylic acid in the presence of a solvent which azeotropically entrains water, and the epoxidation of propylene by this percarboxylic acid solution, characterised in that : a) the organic solution of percaboxylic acid, containing less than 1% by weight of water and up to 1% by weight of hydrogen peroxide, is obtained by reacting, a between 90 and 100 degrees C, a solution of propionic acid in an organic solvent which is inert towards the peracid and capable of forming, with water, a hetero-azeotrope of boiling point below 100 degrees C under atmospheric pressure, with an aqueous solution containing from 30 to 75% by weight of hydrogen peroxide, in the presence of 0.0005 to 0.002 mole of a strongly acid catalyst per mole of hydrogen peroxide and of an inhibitor of radical reactions, and continuously removing the water by azeotropic distillation, the proportions of the reactants being so chosen that the molar ratio of hydrogen peroxide to propionic acid is between 0.2 and 1 and that the azeotropically entraining solvent represents from 50 to 75% by weight of the reaction mixture b) the crude organic solution of perpropionic acid which is obtained as the bottom product from the azeotropic distillation of stage (a) is reacted with an excess of propylene, so that the molar ratio of propylene to perpropionic acid is between 1.01 and 10, at a temperature of between 40 and 80 degrees C, under a pressure of between 2 and 20 bar, the pressure being so chosen that the reaction medium is kept in the liquid phase and c) the reaction mixture issuing from stage (b) is treated in a manner known per se so as to separate off successively unconerted propylene, which is recycled to stage (b), the propylene oxide, which is extracted, the organic solvent and the propionic acid, which are jointly recycled to the peracid synthesis stage (a).
